Example usage

 
<form action="/bin/nph-redir.cgi" method="get"> 
Please select a product category:<br> 
<select name="dest"> 
<option value="/products/handbags.html">Handbags 
<option value="/products/shoes.html">Shoes 
<option value="/products/belts.html">Belts 
<option value="http://www.manufacturer.com/">Manufacturer's site 
</select> 

note: the attribute name="dest" and action="/bin/nph-redir.cgi"cannot be named any other way for this cgi to work.

Frame/window targeting:

Adding target="frame_name" to the <form> tag, like:
<form action="/bin/nph-redir.cgi" method="get" target="main">

It will then redirect to the frame named main. Other options include "_blank" which wil open a new window, and "_top" which will break out of frames.
